Solder heating system
This invention provides a system capable of melting solder and removing the melted solder from a substrate. The heating system includes a desoldering tool having at least two handles, a first handle and a second handle. This way, an operator may grip the first handle or the second handle depending on the operator's preference of gripping the desoldering tool. The first handle has a cavity adapted to releaseably receive a storage where the melted solder can be deposited and stored. The storage may have a divot adapted to receive a key from the first handle so that the storage may be orientated in a predetermined position relative to the cavity. The cavity in the first handle is exposed so that the storage can be readily inserted or replaced. This allows the operator to easily replace and maintain the desoldering tool without a significant downtime. The first handle is adapted to receive a heater cartridge having a transition section to couple the leading section and the electrical cartridge in a staggered manner. This configuration allows the leading section to have a shortened channel that is substantially straight and aligned with the passage formed within the first handle to minimize the resistant to flow of the melted solder through the channel which is then deposited into the storage.
1. Field of the Invention
This invention is directed to a heating system for removing solder from a substrate such as a circuit board. In particular, the heating system is directed to a desoldering tool that provides a tip for melting solder and retrieving the melted solder to a replaceable storage for retaining the solder and providing operators with different options in gripping the desoldering tool.
2. General Background and State of the Art:
Desoldering tools provide heat and vacuum source to a tip in order to melt the solder on a substrate and retrieve the melted solder through the tip. Internally, the desoldering tool has a solder collection chamber where the melted solder is deposited for temporary storage. In addition, the solder collection chamber is provided with a filter to remove the flux from the vapor that accompanies the melted solder so that filtered vapor may be vacuumed away to the vacuum source without clogging the internal mechanism of the desoldering tool. As the melted solder quickly fills the solder collection chamber, the passage to the vacuum source can clog up. This can shorten the desoldering operation and require frequent cleaning or changing of the solder collection chamber. In addition, the solder collection chamber may be integrated into the desoldering tool in such a way that the desoldering tool may need to be disassembled in order to replace or clean the solder collection chamber. This adds to the downtime of the desoldering operation and increases the chance that the desoldering tool is reassembled improperly. The frequent exchange or cleaning of the solder collection chamber also adds to the cost of operating the desoldering tool because of the expense associated with the solder collection chamber.
The desoldering tools are also provided with one grip handle so that operators are limited in the way they can grip the desoldering tools. For example, some soldering tools are provided with a pistol grip while other soldering tools are provided with an elongated housing with a grip on one end. Operators, however, may find that one type of a grip may be more ergonomically comfortable than others. In a large production facility where one type of a grip is provided, some operators may find that the grip is comfortable while many others may find that the same grip is uncomfortable. As such, there still is a need for an improved desoldering tool to efficiently clean or replace the solder collection chamber and provide a grip that is ergonomically comfortable to a variety of operators.
INVENTION SUMMARYThis invention provides a heating system capable of melting solder and removing the melted solder away from a substrate. The heating system includes a desoldering tool having at least a first handle and a second handle. Dividing the desoldering tool into two handles allows an operator to use the desoldering tool in two ways. One way is to operate the first handle independently without the second handle. Another way is to couple the second handle tangentially to the first handle so that an operator can grip the second handle like a pistol. The desoldering tool offers two ways to grip the tool so that operator can grip the first handle or the second handle depending on the operator's preference.
The first handle has a front end and a back end. Along the front end, the first handle is adapted to receive a heater cartridge. The heater cartridge has a leading section with a tip with a channel within the leading section to convey the vacuum source to the tip. In the back end, the first handle receives a power source and a vacuum source, where the power is transmitted to a heater, adjacent to the tip, to convert the power to heat in order to heat the tip. A passage between the vacuum source and the front end of the first handle conveys the vacuum source to the channel within the leading section. This allows the tip to heat the solder and retrieve the melted solder with the vacuum source provided through the channel formed within the leading section. To minimize the resistance to flow of the melted solder, the length of the channel may be minimized and the channel may be substantially straight. In addition, the temperature along the channel may be substantially constant.
To operate the desoldering tool, the first handle may have a first trigger and the second handle may have a second trigger. When only the first handle is used, the first trigger may be used to turn on or off the vacuum source to the tip. When the second handle is used, the second handle may be tangentially coupled to the first handle in such a way that the second trigger is mechanically coupled to the first trigger so that actuation of the second trigger activates the first trigger, which in turn turns on or off the vacuum source to the tip. As such, the first handle may be used independently as a desoldering tool, depending on the working environment and the operator's preference. Optionally, the second handle may be coupled to the underside of the first handle to turn on or off the desoldering tool using the second trigger located on the second handle.
Once the desoldering tool is in operation, the power to the heater may be provided while actuation of the first trigger or the second trigger may turn on or off the vacuum source to the tip. That is, the power provided to the heater may be monitored independently from the operation of the vacuum source so that the heater may provide sufficient heat to the channel to maintain the solder in a melted state so that the solder may flow through the channel.
The first handle may have a cavity adapted to releaseably receive a storage, where the melted solder through the channel can be deposited and stored. The storage may include a filter to capture the dust or vapors from the melted solder that may clog up the passage to the vacuum source in the first handle. The storage may have a divot adapted to receive a key from the first handle so that the storage may be orientated in a predetermined position relative to the cavity. The cavity in the first handle is exposed so that the storage can be readily inserted or replaced. This allows the operator to easily replace and maintain the desoldering tool without significant downtime.
Besides the leading section, the heater cartridge may have an electrical cartridge that couples to the power source to provide power to the heater adjacent to the tip. The heater cartridge has a transition section to couple the leading section to the electrical cartridge so that the longitudinal axis of the leading section is staggered with the longitudinal axis of the electrical cartridge. Such configuration allows the leading section to have a shortened channel that is substantially straight and aligned with the passage formed within the first handle to minimize the resistance to flow of the melted solder and provide an efficient path for the vacuum source. The diameter of the channel may be greater away from the tip to minimize the resistance to flow of the melted solder. In addition, the heater and the leading section may be integrated by bonding the two with ceramic material. This is done to block out air gaps to improve the conduction path from the heater to the tip of the leading section. By improving the conduction or heat transfer from the heater to the tip, the leading section may have a better thermal recovery to rapidly heat the leading tip and the channel.
Other systems, methods, features and advantages of the invention will be or will become apparent to one with skill in the art upon examination of the following figures and detailed description. It is intended that all such additional systems, methods, features and advantages be included within this description, be within the scope of the invention, and be protected by the accompanying claims.
BRIEF DESCRIPTION OF THE DRAWINGSThe invention can be better understood with reference to the following figures. The components in the figures are not necessarily to scale, emphasis instead being placed upon illustrating the principles of the invention. Moreover, in the figures, like reference numerals designate corresponding parts throughout the different views.
As illustrated in
The first handle 12 may also have an engagement member 42 adapted to releaseably couple to the second handle 18. The heating system 10 may be used or without the second handle 18 depending on the operator's preference. Once the desoldering tool is in operation, the power from the power line 34 may be provided to the heater cartridge 16 for heating the solder. The first handle 12 may have a first trigger 43 that may be activated and deactivated to turn on or off the vacuum source, respectively, to the tip of the heater cartridge 16. The second handle 18 may be releaseably coupled to the first handle 12 through the engagement member 42 as illustrated in
The back holder 22 may have an outlet 48 that is coupled to the vacuum source 40. The back holder 22 may be biased against a resistant member 50 to allow the back holder 22 to move between the first position and the second position.
The channel 36 formed between the tip 38 and the pipe 28 may be substantially straight to minimize the resistance to flow of the melted solder through the channel 36. The temperature along the channel 36 may be maintained above the melting temperature of the solder to maintain the solder in a melted state. This way, melted solder removed through the channel 36 remains in the melted state as it flows from the tip 38 through the end of the pipe 28. For instance, a portion of the pipe 28 may be surrounded by a heater 60 to conduct heat to the tip 38 to melt the solder to a liquid state and retrieve the melted solder through the channel 36 within the tip. The temperature along a portion of the channel 36 that is away from the heater 60 may be lower than the portion of the channel 36 that is closer to the heater 60. To maintain the solder in the melted state along the entire length of the channel 36, a portion of the pipe 28 that is away from the heater 60 may be covered with a conducting material 62 to conduct heat from the heater 60 to the portion of channel 36 that is away from the heater 60. This way, the temperature along the channel 36 is maintained above a pre-determined temperature to maintain the solder in a melted state to remove the solder through the end of the pipe 28 and deposited into the storage space 56. For example, the pipe 28 near the front end 54 of the first handle 12 may be surrounded by a bronze material to transfer the heat from the heater 60 to the portion of the pipe 28 that is away from the heater 60.
FIGS. 19 illustrates a heater cartridge remover 132 adapted to engage with the heater cartridge 16 to remove the heater cartridge from the first handle 12 when the heater cartridge is hot. The heater cartridge remover 132 has a holding wall 133 and a hook 135 with a space therebetween. The holding wall 133 and the hook 135 are configured to associate with the bottom side of the transition section 19 so that the space between the holding wall 133 and the hook 135 may receive the first plate 80 (
The desoldering control box 140 may control the supply of power and vacuum to the heating system 10 in the following ways. In general, the heater and the temperature sensor are located near the tip so that the temperature sensor may not accurately reflect the temperature along the entire length of the channel 36. In particular, the pipe 28 may be located further away from the heater than the tip, so that there may be some time delay for temperature near the pipe 28 to rise near the temperature of the tip 38. This means that although the tip 38 may be hot enough to melt the solder on a substrate, the temperature along the channel 36 may not be hot enough to maintain the melted solder from the tip 38 in a melted state along the entire length of the channel 36. As such, solder may solidify within the channel and not pass through the other end of the pipe 28.
Once the desoldering tool is in operation, in step 148, the control box 140 monitors the operation to determine whether the desoldering tool 10 is being turned off or not. If the desoldering tool is being turned off, in step 150, the control box 140 delays turning off the power and vacuum to the desoldering tool until the channel 36 is substantially free of solder. This way, remaining solder does not clog the channel 36 which may hinder the next operation. In step 152, the desoldering tool is turned off after the delay in step 150. The delay may be between about fifteen and about thirty seconds before turning off the desoldering tool. In step 154, if the desoldering tool is not being turned off, the control box 140 monitors the temperature of the tip and provides sufficient power to the heater to maintain the predetermined temperature. Once the desoldering tool 10 is turned off, the control box 140 may proceed to the steps 150 and 152 to turn off the desoldering tool 10.
While various embodiments of the invention have been described, it will be apparent to those of ordinary skill in the art that many more embodiments and implementations are possible within the scope of this invention. For instance, the heating system 10 may be adapted for a soldering tool rather than as a desoldering tool as discussed above. That is, the first handle 12 can be adapted as a soldering iron with a releasable heater cartridge 16. A user may grip the first handle along the back end of the first handle, which is away from the heater cartridge, for a soldering operation without the need for a vacuum source. If the user prefers a pistol grip, the user may couple the second handle 18 to the first handle 12 to grip around the second handle 18. The second handle may couple to the first handle in a variety of ways and in a variety of orientations. For example, the second handle may be snapped onto the first handle and the second handle may be tangential relative to the first handle such that the first handle is substantially perpendicular to the first handle once the first and second handles are coupled together. In addition, once the first handle is coupled to the second handle, the orientation of the second handle may be adjusted relative to the first handle so that a user may grip the second handle in a comfortable manner. Accordingly, the invention is not to be restricted except in light of the attached claims and their equivalents.
